A retransmission scheme for circuit-mode data on wireless links

Abstract

The cellular radio link is characterized by deep fades leading to long error bursts (lasting hundreds of msec). Data transmission over such links results in large packet error rates (in the range 10/sup -3/ to 10/sup -1/). The authors have designed a radio link protocol (RLP) to achieve high throughput on such links. The RLP is based on frequent, complete or partial feedback of the receiver state. Performance results for the US digital cellular TDMA standard show that the scheme can provide the equivalent of 9.6 kbps service per full-rate TDMA channel above a carrier to interference ratio of 18 dB.<>
